Operating mechanism of the organic metal-semiconductor field-effect transistor (OMESFET)

Operating mechanism of the organic metal-semiconductor field-effect transistor (OMESFET)

Organic metal-semiconductor field-effect transistors (OMESFETs) were fabricated with a polycrystalline organic semiconductor (pentacene) and characterized in order to systematically analyze their operation mechanism. Impedance measurements confirmed full depletion of the thick pentacene film (1 m) due to the low doping concentration of unintentional doping (typically less than 10 cm). The nece...

Metal-Oxide-Semiconductor Field Effect Transistor (MOSFET)

The IGFET or MOSFET is a voltage controlled field effect transistor that differs from a JFET in that it has a “Metal Oxide” Gate electrode which is electrically insulated from the main semiconductor n-channel or p-channel by a very thin layer of insulating material usually silicon dioxide, commonly known as glass. This ultra thin insulated metal gate electrode can be thought of as one plate of ...

GaN Metal-Semiconductor Field-Effect Transistor Project II

In this paper, we will discuss the modeling and simulation result of GaN MESFET device with our conventional computer added device simulator MEDICI. We will find out material parameter of GaN so that the device characteristics of simulation fit to experimentally built-on device characteristics. Then we will vary some important device parameters such as gate length, channel doping rate, and acti...

Fast 1 kV metal-oxide-semiconductor field-effect transistor switch

Organic metal engineering for enhanced field-effect transistor performance.

A key device component in organic field-effect transistors (OFETs) is the organic semiconductor/metal interface since it has to ensure efficient charge injection. Traditionally, inorganic metals have been employed in these devices using conventional lithographic fabrication techniques. Metals with low or high work-functions have been selected depending on the type of semiconductor measured and,...
